Jonathan - am I correct in thinking that all the oil pipes go direct to the sliding carriages/ball nuts? Presumably you also had to be careful about routing pipes and allowing enough slack for movement.

Yes and yes, but slack for movement doesn't present much of a challenge as the only pipes that move are the two connected to the gantry, which can be routed with the Y and Z axis motors. The challenge is when you have rotating nuts...

That's fine if you use oil, but I'm on about grease. Tell me this though, does the oil drip about all over the place ? it's okay for you people who cut metal but I'm cutting wood and the last thing I want is oil contaminated wood, that's why I use grease.

If you put plenty of oil in then yes, it goes everywhere. Perhaps it could be managed with more careful control of the quantity.
